Bootstrap V2 Search icon in navbar search

Heres an easy way to display a clickable search icon within twitter bootstraps navbar search field instead of having to use a button and still have the rounded corners for the search field

In a project I was working on, I wanted to put twitter's navbar-search form within the navbar, and I wanted to use an icon within the search box to act like the button. I also wanted to use the rounded corners that the search-query input class has instead of the blocky like search form with the actual button to click. So heres what I came up with to put the search icon in the beginning of the input box that the user can click to submit the form however you'd like.
